l.Application,led September 12, 1923. Serial No. 662,173.5

This invention relates to Aa coffee perco lator7 and more partieularlyto animproved manner .of constructing and ysupportinghthe,

. lators of this type the weight `of 'the contents in the basket together with the weight of 4the basketxitselthas always been sustained by the perforatedbottom of the basket, Aand which,"by lreason of the perforations therein has been weakened to such an extent thatin manyinstances the botto-m has collapsed or broken through. It is` the primaryobject olithe presentinventionto overcome thisidiinculty by providing. an improved basketsupport4 construcr tion in which the weight of theA basket isA entirely supportedubyan inverted arch lmeniber having its outer ends secured to the bottom of thebasket adjacentthe outer walls thereoll and havin'g'a .central connectionby means ofwvhich the Aarch member `is supported on the stem. y

A further object of the inventionis to prolvide a strong and etlicientl construction-of a basket sup-port. l

These?. and other .objectsare obtained by providingfa `construction and an arrangement of t-he Various partsl in the manner hereinafter described and particularly point.

. the entire weight of the ooil'ee Lbasket is ened out in the appended claims.

Referring tothe drawing:

By this construction j tirely sustained by the outer edges of the bottom of the basket by the inverted arch member, which in turn rests on the embossed vbead 21 of the stem 14. The upper portion of the stem 14, as shown alt- 22 extends bead 27. By referring to Fig. 1 it will be noted that the basket 18 is positioned within the percolator proper or receptacle 5 and is entirely supported on the stem 14 through the medium'of the inverted arch support 15 having its horizontal portion 19 engaging the embossed bead 21 of the stem 14. i

,By this construction we have provided a very' efficient land yetsimple construction of coffee container and support therefor, which will preclude the possibility vof crushing the perforated bottom as commonly experienced in devices of this type. ,e

VVhile in the above specification we have described one embodiment which our invention may assume in practice, it will be understood `that various other forms may be made and be within the contemplation of our invention. i

Vhat we claim as our invention and desire to secure by Letters Patent is:

1. A coffee percolator comprising a receptacle, a tubular stem mounted on the bottom of the receptacle and being supported thereby, an annular enlarged portion on the stem adjacent its upper end, a coffee `basket provided with a central tubular portion adapted to. telescope over the upper end of said tubular stem, means for supporting the said coffee basket on the upper end of said tubular stem comprising a unitary inverted arch member comprising a perforated intermediatel portion adapted 'to be spaced apart from the bottom of the said coffee basket in contact with the said enlarged annular portion on the tubular stem, and extensions on the said arch member on diametrically opposite sides of the tubular member extending radially upwardly to the bottom of the basket and secured thereto adjacent the Vouter periphery of the basket.

2. The combination in a coffee percolator comprising a receptacle, of a tubular stem mounted in the bottom of said receptacle and extending toward the top thereof, an annular enlarged portion formed integrally with said tubular stem intermediate `the ends of said stem, a coffee basket having a tubular member secured centrally in the bottom thereof and forming a telescoping connection with said stem on the end there- .of above the said annular enlarged portion,

and a unitary supporting member in the form of an inverted arch comprising an enlarged intermediate portion perforated to telescope over the tubular lmember and to rest in a horizontal positionon the top of said enlarged annular portion of the tubular member, the end portions thereof being extended on diagrammatically opposite sides of the tubular member upwardly from the said intermediate portion to the bottom'of the coffee basket and thence deflected hori- Zontally andV secured to the bottom of said basket for rotatably and detachably securing the said basket in position to be supported on the vupper end of said tubular `member.

3. As an. article of manufacture, a coffee basket for percolators comprising. a sheet metal receptacle of substantially cylindri-4 cal form, the bottom thereof being provided with a central perforation adapted to telescope overthe upper end of a tubular support for said basket, and a bracket comprising a member formedof sheet metal hav` Y ing a perforated intermediate portion adapted to be spaced apart from the bottom of thel said basket` the said intermediate portion lying in a plane approximately parallel with the bottom of the basket and Vbeing adapted to be supported on thetop of an annular enlargement on the tubular stem of a per'- colator,.the diagrammatically opposite ends of the said supporting member 'being eX- tended upwardly and outwardly beyond the.
